Juniper Exam JN0-636 Topic 8 Question 27 Discussion

To solve the problem of the operator user being unable to save configuration files to a USB stick that is plugged into SRX, you need to add the system-control permission flag to the operations class. The other options are incorrect because:

A) Adding the floppy permission flag to the operations class is not sufficient or necessary to save configuration files to a USB stick. The floppy permission flag allows the user to access the floppy drive, but not the USB drive.The USB drive is accessed by the system permission flag, which is already included in the operations class1.

C) Adding the interface-control permission flag to the operations class is also not sufficient or necessary to save configuration files to a USB stick. The interface-control permission flag allows the user to configure and monitor interfaces, but not to save configuration files.The configuration permission flag, which is also already included in the operations class, allows the user to save configuration files1.

D) Adding the system permission flag to the operations class is redundant and ineffective to save configuration files to a USB stick. The system permission flag allows the user to access the system directory, which includes the USB drive.However, the operations class already has the system permission flag by default1. The problem is not the lack of system permission, but the lack of system-control permission.

Therefore, the correct answer is B. You need to add the system-control permission flag to the operations class to solve the problem.The system-control permission flag allows the user to perform system-level operations, such as rebooting, halting, or snapshotting the device1.These operations are required to mount, unmount, and copy files to and from the USB drive2. To add the system-control permission flag to the operations class, you need to perform the following steps:

Enter the configuration mode: user@host> configure

Navigate to the system login class hierarchy: user@host# edit system login class operations

Add the system-control permission flag: user@host# set permissions system-control

Commit the changes: user@host# commit

login (System)
